1 Topical Fire Report Series Volume 9, Issue 4 / May 2009 Medical Facility Fires These short topical reports are designed to explore facets of the U.S. fire problem as depicted through data collected in USFA s National Fire Incident Reporting System (NFIRS). Each topical report briefly addresses the nature of the specific fire or fire-related topic, highlights important findings from the data, and may suggest other resources to consider for further information. Also included are recent examples of fire incidents that demonstrate some of the issues addressed in the report or that put the report topic in context. Findings Between 2004 and 2006, an average of 6,400 fires occurred in medical facilities each year, resulting in over $34 million in losses. Fifty-five percent of medical facility fires are small, confined cooking fires. Medical facilities offering 24-hour care account for 89 percent of medical facility fires. Twenty-four-hour care facilities also account for 94 percent of cooking fires in all medical facilities. Fire peaks coincide with meal preparation times. Automatic extinguishing systems are found more often in 24-hour care facilities than in clinics or medical offices. Between 2004 and 2006, there was an average of 6,400 fires in medical facilities each year that were responsible for approximately 5 civilian fire deaths, 175 injuries, and $34 million in property loss annually. 1 Medical facilities include hospitals, clinics, infirmaries, and other facilities that provide care to the sick and injured. Fires in these buildings 2 can be particularly dangerous due to the presence of oxygen and other flammable substances and the challenge of evacuating patients who may not be ambulatory. This topical report focuses on fires in medical facilities that were reported to the National Fire Incident Reporting System (NFIRS) between 2004 and 2006 and examines the causes and basic characteristics of these fires. Loss Measures Table 1 compares the loss measures for fires in medical facilities, averaged over this 3-year period, to those in nonresidential buildings. 3 Table 1.

3 TFRS Volume 9, Issue 4/Medical Facility Fires Page 3 When Fires Start Between 2004 and 2006, medical facility fires occurred somewhat uniformly throughout the year, with a slight decrease during the summer months of June through August. January, March, October, and December had the highest percentages of fire with approximately 9 percent each. (Figure 2). Figure 2. Medical Facility Fires by Month (2004 to 2006). 11,737 incidents Very few medical facility fires occur late at night and early in the morning. As noted in Figure 3, medical facility fires were lowest in the very early morning between 3 a.m. and 4 a.m. Fires increased sharply between 6 a.m. and 8 a.m., and continued to increase slightly until a peak of approximately 7 percent from 11 a.m. to noon. The number of fires decreased in the early afternoon and peaked a second time in the late afternoon between 4 p.m. and 5 p.m. These periods of fire incidence coincide with the morning and evening cooking periods.

4 TFRS Volume 9, Issue 4/Medical Facility Fires Page 4 Figure 3. Medical Facility Fires by Time of Day ( ). 11,737 incidents Type of Fire Building fires consist of two major categories of incidents: fires that are confined to specific types of equipment or objects (confined fires) and those that are not (nonconfined fires). Confined building fires are small fire incidents that are limited in scope, confined to noncombustible containers, rarely result in serious injury or large content losses, and are expected to have no significant accompanying property losses due to flame damage. 4 Sixty-five percent of medical facility building fires are these small fires as shown in Table 2. Confined cooking fires alone account for 55 percent of medical facility fires. Twenty-four-hour care facilities account for 94 percent of confined cooking fires in medical facilities (as well as 94 percent of all cooking fires, both confined and nonconfined fires, in medical facilities.)

Medical Facility Fires by Type of Incident (2004 to 2006) Incident Type Percent Nonconfined fires 34.6 Confined fires 65.4 Cooking fire, confined to container 55.0 Chimney or flue fire, confined to chimney or flue 0.5 Incinerator overload or malfunction, fire confined 0.3 Fuel burner/boiler malfunction, fire confined 2.9 Commercial compactor fire, confined to rubbish 0.3 Trash or rubbish fire, contained 6.3 Total ,737 incidents Note: Total may not add to 100 percent due to rounding Confined fires are allowed abbreviated NFIRS reporting and many reporting details of the fire are not required. The remainder of this topical report will address nonconfined medical facility fires, except for the smoke alarm data analyses where confined fires are examined also. Causes of Nonconfined Medical Facility Fires While cooking is undoubtedly the leading cause of fires in medical facilities overall (64 percent), it plays a very small role in medical facility nonconfined fires. As shown in Figure 4, electrical malfunction (19 percent), appliances (15 percent), and equipment misoperation (13 percent) are the leading causes of nonconfined fires in medical facilities. These three causes account for 47 percent of the nonconfined fires in medical facilities when the cause is known. In 23 percent of medical facility fires, the cause is unknown. In the 26 percent of fires where the equipment involved in the fire ignition is specified, clothes dryers were reported as the leading equipment involved (26 Percent). Figure 4. Cause of Nonconfined Medical Facility Fires (2004 to 2006). 4,065 incidents 950 incidents with unknown cause of fire

6 TFRS Volume 9, Issue 4/Medical Facility Fires Page 6 Where Fires Start Area of Fire Origin in Nonconfined Medical Facility Fires As shown in Table 3, the three leading areas of fire origin laundry area, bedrooms, and kitchens reflect the predominance of 24-hour care facilities in medical facility fires. The laundry area is the leading area of origin of nonconfined medical facility fires (15 percent), followed closely by bedrooms (14 percent). Kitchens and other cooking areas are the third leading area of fire origin, accounting for 10 percent of medical facility fires. Table 3. Leading Areas of Fire Origin in Nonconfined Medical Facility Fires (2004 to 2006) Area of Fire Origin Percent of Nonconfined Medical Facility Fires Laundry area, wash house (laundry) 15% Bedrooms 14% What Ignites Nonconfined Medical Facility Fires The category general materials is the leading category of items first ignited and accounts for 31 percent of nonconfined medical facility fires. Within this category, the insulation around electrical wiring is the leading type of item first ignited overall, accounting for 18 percent of all medical facility fires. This finding is consistent with electrical malfunction as the leading cause of nonconfined medical facility fires. Soft goods (such as linens) and wearing apparel are the items first ignited in 23 percent of medical facility fires. Another leading category of items first ignited, as seen in Figure 5, is structural components or finishes (16 percent). This includes insulation, roofing, doors, carpets, and the like, though none of these subcomponents alone account for a large portion of nonconfined medical facility fires. Cooking area, kitchen 10% 4,065 incidents 185 incidents with area of origin undetermined Note: Percentages reflect those incidents where area of fire origin was determined.

Item First Ignited in Nonconfined Medical Facility Fires (2004 to 2006). 4,065 incidents 919 incidents with item first ignited undetermined Heat Source for Nonconfined Medical Facility Fires A clear majority of nonconfined medical facility fires derive their heat source from powered equipment (66 percent). The subcomponents of this category are the leading sources of heat, not only within this category, but also in all nonconfined medical facility fires: unspecified types of powered equipment are responsible for 24 percent of all fires; electrical arcing 18 percent; radiated or conducted heat from powered equipment 17 percent; and sparks from operating equipment 7 percent. (Figure 6.) The next leading category of heat sources in nonconfined medical facility fires is heat from other open flames or smoking materials (16 percent). Within this category, the most prevalent source of heat is from cigarettes, accounting for approximately 5 percent of all nonconfined medical facility fires.

Sources of Heat in Nonconfined Medical Facility Fires (2004 to 2006). 4,065 incidents 759 incidents with heat source undetermined Factors Contributing to Ignition in Nonconfined Medical Facility Fires Thirty-one percent of nonconfined medical facility fires are the result of an electrical failure or malfunction as shown in Figure 7. The most common form of electrical failure in this category is other, unspecified electrical failures or malfunctions, which are responsible for 12 percent of all medical facility fires. The next leading category is the misuse of materials at 28 percent. Within this category, heat sources that are left too close to combustibles account for 9 percent of all medical facility fires, and abandoned or discarded materials account for 7 percent.

Factors Contributing to the Ignition of Nonconfined Medical Facility Fires (2004 to 2006). 2,312 incidents where factors contributing to ignition were specified Note: Includes only incidents where factors that contributed to the ignition of the fire were specified. Multiple factors contributing to fire ignition may be noted for each incident. Total may sum to more than 100 percent. Suppression/Alerting Systems in Medical Facility Fires Smoke alarms were present in 80 percent of nonconfined medical facility fires and are known to have operated in 55 percent of the nonconfined medical facility fires. Only 11 percent of nonconfined fires in medical facilities had no smoke alarms present in the building at the time of the fire (Table 4). In another 9 percent of these fires, firefighters were unable to determine if a smoke alarm was present. In 22 percent of fires where smoke alarms were present, the alarms failed to operate because either the fire was too small to activate the alarm or the alarm did not operate properly.

11 TFRS Volume 9, Issue 4/Medical Facility Fires Page 11 Table 6. NFIRS Smoke Alarm Data for Confined Medical Facility Fires (2004 to 2006) Smoke Alarm Effectiveness Count Percent Smoke alarm alerted occupants 5, Smoke alarm did not alert occupants Unknown 1, Total incidents 7, ,672 incidents Note: The data presented in Table 6 are raw data counts from the NFIRS data set. They do not represent national estimates of smoke alarms in confined medical facility fires. They are presented for informational purposes. Total may not add to 100 percent due to rounding. Note that the data presented in Tables 4, 5, and 6 are the raw counts from the NFIRS data set and are not scaled to national estimates of smoke alarms and AES in medical facility fires. Examples May 2006: The Mercy Surgical and Diagnostic Center in California caught fire and had an estimated $750,000 of damage to the building before firefighters could put out the fire. Investigators believe the fire was arson. 6 December 2006: A fire began in an exam room in the medical clinic of Lansing s Cristo Rey Community Center. Of the 10 rooms, 2 were completely destroyed, 3 were badly damaged, and the remaining 5 had either smoke or water damage. Investigators believe the fire was started either as a result of an electrical malfunction, or arson. 7 March 2009: A carelessly discarded cigarette is suspected to have started a mid-afternoon fire, heavily damaging a professional building that housed medical offices. The flames began outside the one-story brick building and entered through the eaves. The structure appeared to be a total loss, although medical records inside were thought to be salvageable. Thirteen employees and several patients evacuated without injury as flames spread quickly. 8 Conclusions Medical facility fires affect a vulnerable population, as many patients in medical facilities may not have the independence to escape a fire incident. Thus, proper care must be taken to ensure that safety measures and regulations are adhered to for all medical facilities. Routine fire escape drills must be practiced and all medical staff must be trained and responsible in the event of a fire emergency. It also may be beneficial for medical facility personnel to look into nonflammable or flame-retardant materials to use in hospitals, especially in terms of bedding and gowns, since many medical facility fires start in laundry rooms and bedrooms and on items such as linens and apparel.

12 TFRS Volume 9, Issue 4/Medical Facility Fires Page 12 NFIRS Data Specifications for Medical Facility Fires Data for this report were extracted from the NFIRS annual public data release (PDR) files for 2004, 2005, and Only version 5.0 data were extracted. Medical facility fires were defined as: Incident types 111 to 123: Incident Type Description 111 Building fire 112 Fires in structure other than in a building 113 Cooking fire, confined to container 114 Chimney or flue fire, confined to chimney or flue 115 Incinerator overload or malfunction, fire confined 116 Fuel burner/boiler malfunction, fire confined 117 Commercial compactor fire, confined to rubbish 118 Trash or rubbish fire, contained 120 Fire in mobile property used as a fixed structure, other 121 Fire in mobile home used as fixed residence 122 Fire in motor home, camper, recreational vehicle 123 Fire in portable building, fixed location Property Use Description Nursing homes licensed by the State, providing 24-hour nursing care for four or more persons. Mental retardation/development disability facility that houses, on a 24-hour basis, four or more persons. Alcohol or substance abuse recovery center where four or more persons who are incapable of self-preservation are housed on a 24-hour basis. Asylum, mental institution. Includes facilities for the criminally insane. Must include sleeping facilities. Hospital: medical, pediatrics, psychiatric. Includes hospital-type infirmaries and specialty hospitals where treatment is provided on a 24-hour basis. Hospices.

Note: Incident types 113 to 118 do not specify if the structure is a building. Incident type 112 is included as previous analyses have showed that incident types 111 and 112 are used interchangeably. Aid types 3 (mutual aid given) and 4 (automatic aid given) were excluded to avoid double counting of incidents. Property use 311 to 343: Structure type: o 1--Enclosed building, o 2--Fixed portable or mobile structure, and o Structure type not specified (null entry).

13 TFRS Volume 9, Issue 4/Medical Facility Fires Page 13 Notes: 1 National estimates are based on data from the National Fire Incident Reporting System (NFIRS) (2004 to 2006) and nonresidential structure fire loss estimates from the National Fire Protection Association s (NFPA s) annual survey, Fire Loss in the United States. Fires are rounded to the nearest 100, deaths to the nearest 5, injuries to the nearest 25, and loss to the nearest million dollars. 2 In the NFIRS version 5.0, a structure is a constructed item of which a building is one type. To coincide with this concept, the definition of a building fire for NFIRS 5.0 has, therefore, changed to include only those fires where the NFIRS 5.0 structure type is 1 or 2 (enclosed building and fixed portable or mobile structure). Such fires are referred to as buildings to distinguish these buildings from other structures that may include such structures as fences, sheds, towers, and bridges in addition to many other constructed items. In addition, incidents that do not have a structure type specified are presumed to be buildings. 3 The average annual fire death and injury loss rates computed from the national estimates will not agree with average fire death and injury loss rates computed from NFIRS data alone. The average annual fire death rate computed from national estimates would be (1000*(5/6,400)) =.8 deaths per 1,000 medical facility fires and the average annual fire injury rate would be (1000*(175/6,400)) = 27.3 injuries per 1,000 medical facility fires. 4 NFIRS distinguishes between content and property loss. Content loss includes loss to the contents of a structure due to damage by fire, smoke, water, and overhaul. Property loss includes losses to the structure itself or to the property itself. Total loss is the sum of the content loss and the property loss. For confined fires, the expectation is that the fire did not spread beyond the container (or rubbish for incident type 118) and hence, there was no property damage (damage to the structure itself) from the flames. However, there could be property damage as a result of smoke, water, and overhaul. 5 In confined fires, the entry smoke alarm did not alert occupants can mean: no smoke alarm was present, the smoke alarm was present but did not operate, or the smoke alarm was present and operated but the occupant was already aware of the fire. 6 Arson Suspected in Merced Clinic Fire, ABC30.com, May 29, 2006, local&id= (accessed July 23, 2008). 7 Lori Dougovito, Fire at Cristo Rey May be Arson, Medical Center Damaged, wilx.com, December 7, 2006, news/headlines/ html (accessed July 23, 2008). 8 Robert Kelly, Cigarette Is Linked to Fire in Building at Edwardsville Business Center, St. Louis Post-Dispatch, STLtoday. com, March 17, 2009, stories.nsf/illinoisnews/story/a27410be97f53ff c007 74B92?OpenDocument (accessed March 17, 2009).
